Abstract
The aluminum alloy rocker arm comprises a rocker arm body and a rocker arm insert, wherein the rocker arm insert is fixed at one end of the rocker arm body, a valve adjusting bolt hole is formed in the other end of the rocker arm body, and the rocker arm body and the rocker arm insert are made of 7XXX series aluminum alloy and 15Cr steel respectively. The design has the advantages of light weight, good performance and low production and processing cost.
Description
Technical field
The utility model relates to engine valve actuations mechanism, particularly relates to a kind of Big Mutha Truckers engine aluminum alloy rocking arm, is specifically applicable to weight reduction, improves performance, reduces costs.
Background technique
Rocking arm is one of critical component of engine valve actuating mechanism, need to possess the feature such as the impact of high frequency tolerant rate, high strength, rotary inertia be little, and the requirement of truck engine to rocking arm is higher.
Chinese patent: Authorization Notice No. is CN201074532Y, the day for announcing is that the utility model patent on June 18th, 2008 discloses a kind of valve actuating mechanism of rocker type engine, comprise rocking arm, pitman arm shaft, rocking arm insert and air valve yoke; rocking arm insert is fixed on rocking arm head, linear contact lay between rocking arm insert lower end and air valve yoke.In said structure, generally adopt 40Cr or the 20CrMo steel of quenching with Subsequent tempering when rocking arm applies to Big Mutha Truckers motor, this material is forging and molding under 1200 DEG C of high temperature, and plastic deformation resistance is large, energy consumption is high, difficulty of processing is large, and preparation cost is higher; In addition, steel rocking arm Heavy Weight, in movement process, rotary inertia is large, and this not only causes engine operation noise large, and engine power loss is increased.
Summary of the invention
The purpose of this utility model overcomes the quality weight of prior art existence, the problem of poor-performing, provides the Big Mutha Truckers engine aluminum alloy rocking arm that a kind of quality is light, performance is good.
For realizing above object, the technical solution of the utility model is as follows:
A kind of Big Mutha Truckers engine aluminum alloy rocking arm, comprise rocking arm body, rocking arm insert, described rocking arm insert is fixed on one end of rocking arm body, and the other end of rocking arm body offers valve adjustments bolt hole;
The manufactured materials of described rocking arm body is 7XXX line aluminium alloy.
The manufactured materials of described rocking arm insert is 15Cr steel.
The inside of described rocking arm body offers oil duct, and one end of this oil duct communicates with the outside oil circuit of rocking arm body, extends to the outside of rocking arm body after the other end of oil duct passes valve adjustments bolt hole, rocker shaft hole successively.
The middle part of described rocking arm body offers rocker shaft hole, is equipped with copper alloy bushing in this rocker shaft hole.
Described valve adjustments bolt hole is thread-rolling screw hole.
Compared with prior art, the beneficial effects of the utility model are:
In a kind of Big Mutha Truckers engine aluminum alloy of the utility model rocking arm, the manufactured materials of rocking arm body is 7XXX line aluminium alloy, this aluminum alloy material not only quality is light, and intensity is high, its strength and toughness reaches the rank of aircraft aluminum, can significantly reduce rocking arm rotator inertia, promotes the inlet and outlet efficiency of motor, reduce engine power loss, reduce engine noise, meanwhile, its produce and processing cost lower than forged steel material.Therefore, not only quality is light for the utility model, performance is good, and produce and processing cost low.
